Yeah, I thoroughly disagree.
I’m skeptical of your assessment that Polish people just aren’t racist at all, and I disagree with your splitting hairs between racism and xenophobia.
But beyond that, I’m baffled as to how you don’t see that in a discussion of the benefits of living in a diverse culture, xenophobia based on ethnicity being linked to a religion and then unfairly conflated with terrorism to justify mistreatment is the exact kind of problem I’m concerned with.
Diversity doesn’t just mean racial diversity, though it appears that Polish people aren’t as comfortable with that either as you’d like to believe.
wouldn’t it be enough to explain to children that racism is just an unscientific, morally abhorrent belief
If history is any guide, no.
Your example about the mathematicians makes me wonder if we’re even talking about the same thing. I don’t want my daughter seeing women mathematicians because I want her to believe their presence will make any team that they’re a part of better (even if true). I want her to see women who are mathematicians so she internalizes the idea that it’s a viable option. The “just tell her it is, even if the world around her tells her the opposite every day” is a recipe for failure. I want her to see it.
